ROBERT ANGUS GILLIES, OF RAYMOND, ALBERTA, CANADA.

AUTOMOBILE-TANK.

To all whom it may concern:

Be it known that I, ROBERT ANGUS GILLIns, of the town of Raymond, in the Province of Alberta, Canada, have invented certain new and useful Improvements in Automobile-Tanks, of which the following is the specification.

The invention relates to an improvement in tanks especially designed forusefor containing gasolene and other such volatile liquids as used for automobiles and such machines.

The object of the invention is two-fold, primarily to provide a means for straining the gasolene withdrawn from the tank and thereby effectively excluding foreign material and secondly, to provide a means for removing water from the gasolene contained in the tank.

With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims.

Figure 1 represents a side view of a tank supplied with my invention. Fig. 2 represents a longitudinal vertical sectional view centrally through the tank. Fig. 3 represents an enlarged detailed vertical sectional view through the valve and adjoining parts, the section being taken at right angles to the section appearing in Fig. 2 of the drawing. Fig. 4 represents a plan view of the cage located in the bottom of the tank. Fig. 5 represents an enlarged detailed vertlcal sectional view through a portion of the cage.-

In the drawing like characters of reference indicate corresponding parts in each figure. j

1 represents a suitable tank for the recepgasolene or other such like volatile liquids.

2 represents a screw cap or filling plug located on the top of the tank and 3 represents a draw off or feed pipe opening at 4 to the bottom of the tank.

5 is an annular base plate secured to the bottom of the tank and surrounding the opening 4. This plate has the upper edge thereof bent outwardl I curled flange 6 the ob ect of which will be 7 represents a more or less coneor dome shaped cage formed from individual wires 8 having their upper ends all connected together at the point 9 and their lower ends Specification of Letters Patent.

- fastened in any suitable way such by brazing or soldering to the inner side of the flange at 10.

11 represents a straining material such as chamois drawn tightly over the cage and havlng the edge thereof fastened to the plate 5 by a wire 12 passed around the flange. It w1ll be understood that when the wire is drawn up taut and fastened the flange will prevent it from being pulled off and consequently will hold the chamois tightly. The gasolene placed in the tank is filtered or strained through the chamois prior to entering the feed pipe 3. I find that chamois has the advantage that it will allow gasolene to strain through but will exclude any water contained within the gasolene. According to the dome-shape of the cage it is impossible for the device to become clogged or choked as the gasolene will wash oil any foreign material collecting as it is agitated in the tank when the automobile is running over the various uneven surfaces encountered when in use.

13 represents a draw ofi pipe carried by a cap screw 14 screw threaded onto an out-v turned flange 15 located on the bottom of the tank, the flange opening to the interior of the tank. The lower end of the draw-off pipe receives the threaded shank 16 of a stop cook 17 and the upper end protrudes a short distance through the cap screw and provides a valve seat 13. The pipe carries a cross spider 18 and also a bracket 19, the bracket and spider forming the bearings for the stem 20 of a valve 21 which valve is arranged to seat on the valve seat 13' formed at the upper end of the draw-ofi' pipe. It is here to be noticed that the pipe protrudes through the cap screw a short distance so that the valve when seated is free of the inner face of the ca screw. The valve is formed from 'two disks, a top disk 22 of metal such as aluminium and a bottom disk 23 of a light material such as-cork. The lower end of the valve stem is enlarged or formed with a knob 24 to prevent the valve from escaping.

The parts just described are for the purpose of allowing the attendant to remove or draw ofl any water which may accumulate in the tank. Any water mixed with the gasolene in the tank will locate at the bottom of the tank, the gasolene floating, so to speak, on top. Assuming a quantity of water has collected in the bottom of the tank, this water will cause the valve to float, it being understood that the proportion of the cork to the aluminium is designed so that the valve will float in water. Immediately the valve floats it passes away from the seat and the water is consequently drained through the stop cock. I Upon the water draining ofi", the valve seats, as the proportion of the aluminium to the cork is designed so that, it will not float in gasolene. The device accordingly provides an automatic means for removing the water contained in the gasolene.

What I claim as my invention is 1. The combination with a tank having an out turned flange, of a cap screw on said flange, a draw oif pipe attached to said cap screw opening to the interior of the tank and providing at the upper end and at the entrance to the tank a valve seat and a valve operating on the valve seat, said valve seat being slightly above the bottom inner face of said cap screw, the specific gravity of the valve being such that it sinks in gasolene and floats in water.

' 2. The combination with a tank, of a draw ofi' pipe opening to the bottom of the tank and presenting a valve seat at the point where it opens to the tank, a spider and a bracket located in the pipe, a valve stem slidably mounted in the bracket and the spider and a valve mounted on the stem and arranged to seat on the valve seat aforesaid, the specific gravity of the valve being such that it sinks in gasolene and floats in water.

3. The combination with a tank, of a draw ofi pipe opening to the bottom of the tank and presenting a valve seat at the point where it opens to the tank, a spider and a bracket located in the pipe, a valve stem slidably mounted in the bracket and the spider and a valve carried by the stem and arranged to seat on the valve seat aforesaid, said valve being formed from connected disks, one of light material such as cork and the other of a heavier material such as aluminium, the proportions of cork and aluminium being such that the valve sinks in gasolene and' floats in water.

4. The combination with the bottom of a tank provided with an out-turned screw threaded flange, of a cap screw fitted on the flange, a drain pipe carried by the cap screw and opening to the interior of the tank, said drain pipe protruding a short distance through the cap screw and having the upper end thereof providing a valve seat, a spider and a bracket located in the pipe, a valve stem slidably mounted in the bracket and the spider and a valve mounted on the stem and operating on the seat, the specific gravity of the valve being such that it sinks in gasolene and floats in water.
